I got one problem I have some data in local storage. Now i have set iframe with another website. I need to pass local data into form inside iframe. but it gives me Cross Site permission issue. Any suggestions.?

Don't use a iframe, sessions will get lost, security settings in browsers change. I once build an application that uses an iframe(8 years ago) and every year it starts failing again because of security settings or other random stuff.

use cURL?

@mattwebdev i cannot use curl since the url is only accessible within the country. So it has to on client side. and server is not in the same country

@helloworld Thanks for the suggestion will try.
